Traditionally, total hip arthroplasty (THA) templating has been performed on anteroposterior (AP) pelvis radiographs. Recently, additional AP hip radiographs have been recommended for accurate measurement of the femoral offset (FO). To verify this claim, this study aimed to establish quantitative data of the measurement error of the FO in relation to leg position and X-ray source position using a newly developed geometric model and clinical data. We analyzed the FOs measured on AP hip and pelvis radiographs in a prospective consecutive series of 55 patients undergoing unilateral primary THA for hip osteoarthritis. To determine sample size, a power analysis was performed. Patients’ position and X-ray beam setting followed a standardized protocol to achieve reproducible projections. All images were calibrated with the KingMark calibration system. In addition, a geometric model was created to evaluate both the effects of leg position (rotation and abduction/adduction) and the effects of X-ray source position on FO measurement.Aims
Methods
A “Clinical Incident Data Collection Form” has been developed to collect and analyse different classifications such as potential risks, near misses, clinical incident, equipment failure and drug error. Trauma, Orthopaedic and Emergency speciality trigger lists will be set up. A Research Officer is in post and a Multidisciplinary Steering Group has been developed, and speciality links have been established. An education programme has commenced for multidisciplinary staff. The aim is to design and test the Clinical Risk Management in action in order to control and reduce risk in clinical care in the Trauma &
Orthopaedic and A&
E Department in Sligo General Hospital.
